USGS Water-Year Summary 2022
LOCATION - Lat 44°29'33", long 121°17'50" referenced to North American Datum of 1927, in NW 1/4 NE 1/4 sec.33, T.12 S., R.12 E., Jefferson County, OR, Hydrologic Unit 17070305, on right bank, 0.2 mi downstream from Opal Springs, 4.8 mi southwest of Culver and at mile 6.7.
DRAINAGE AREA - 4,557 mi². approximately, of which 500 mi² is probably noncontributing.
PERIOD OF RECORD - October 1961 to current year.
GAGE - Water-stage recorder. Datum of gage is 1,953.60 ft above NGVD of 1929 (Portland General Electric Co. bench mark).
REMARKS - Flow regulated by Prineville Reservoir (active capacity, 148,600 acre-ft, from survey completed in 1998) and Ochoco Reservoir (active capacity, 39,600 acre-ft, from survey completed in 1990). Dam and powerplant 0.3 mi upstream, completed in 1985, causes brief fluctuations in flow. Many diversions for irrigation upstream from station. Practically all of summer flow comes from Opal Springs and other springs within 15 mi upstream from station. Simultaneous records (1961-63) at former gaging station 5.6 mi downstream indicated over 15 percent increase to summer flow from springs downstream from this station.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 6,660 ft³/s Dec. 24, 1964, gage height, 9.36 ft; minimum discharge since October 1989, 630 ft³/s Feb. 19, 2016; minimum daily discharge, 1,090 ft³/s May 11, 1981.
PERIOD OF RECORD - WATER TEMPERATURE: October 1963 to September 1974, November 2005 to current year.
INSTRUMENTATION - Temperature probe and data logger.
EXTREMES FOR PERIOD OF DAILY RECORD - WATER TEMPERATURE: Maximum, 15.0°C on many days in water years 1964 and 1969, May 31, 2015; minimum, 4.0°C Dec. 29, 30, 1964.
